It took me a while to figure out how to parse a 10 digit zip into 5. The code is likely extraneous, but I'm new at this and it worked. I code takes a field from a database ( in this case a zip code database with 10 digit zips demaracated by a "-") parses the data into an arrays of 5 and 4 digits and then loads the data into a predifined field for zip 5 digits.

<?php


$cnx = mysql_connect('localhost','username','password');
mysql_select_db('db');


$query = @mysql_query("select * from zips");


while($zips = mysql_fetch_array($query) ) {
$zip = $zips['zip'];
$id = $zips['id'];
$zipsplit = explode ('-', $zip);
$zip5 = $zipsplit[0];
$zip4 = $zipsplit[1];

$update = "update zips set zip5='".addslashes($zip5)."' where $id=id";

if (@mysql_query($update)) {
echo('<p>New Information added</p>');
} else {
echo('<p>nope: ' .
mysql_error() . '</p>');
}
}
?>
